Just an example to show some capability - done in 6.0.2 The idea came from a Fusion 360 online video.
DSM although basic in tools can still accomplish some decent shapes with good blends and edge rounds. The zebra strips show good surface transitions handled by the Parasolid kernal.
DSM can't descriptively do G2 surface continuity, but for practical purposes for many molding purposes this is accurate surface modelling.
Note the strips transitioning over the surface edges...

To refine the shape, modify the layout curves and re make the surfaces.
The new universal Instant mirror tool is very handy - good tangency over the reflected handle halves
